"He's a young player who we've been tracking for a while now," said Head Coach Sigi Schmid. "He has a very good left foot and a good shot from distance. Martinez can play wide and can also play underneath the front runners. He is pretty technical and a player who we think has a big upside."

Martinez, 23, is currently playing for Honduras in the 2012 London Olympics, marking his second Olympics after participating in the 2008 Beijing games as a 19-year-old. Honduras has qualified for the quarterfinals after drawing with Morocco and Japan and beating Spain.

"I would like to thank our head scout, Kurt Schmid, and Mario's agent, Horatio Patanian, who worked very hard to get this deal over the finish line," said Owner and General Manager Adrian Hanauer. "We are very excited to have Mario join our team, following the Olympics."
